[0002] During the overhauling of an internal combustion locomotive, it is common to dismount the diesel engine. Since the side plate crossbeam is above the diesel engine, the crossbeam needs to be removed before the diesel engine is lifted off. However, during actual overhauling, many obstacles may occur. For example, after the side plate crossbeam of a 240-type internal combustion locomotive is removed, the side plate is prone to deformation due to its length. During the reinstallation of the crossbeam, the deformed side plate often makes it difficult to accurately align the mounting holes of the side plate and the crossbeam, thus preventing smooth installation.
